I have had a FZ150 for 10 months and love it. I recently bought a FZ200 at Amazon for my wife. Our experience is that JPEG image quality is nearly identical. The two major differences are: (1) The electronic viewfinder on the FZ200 is significantly superior (many more pixels). (2) The FZ200 has aperture f2.8 available at all zoom lengths. This can be significant for motion photos at long focal lengths. It does not impact us because we use long focal lengths primarily for close-ups of botanical subjects generally at f5.6.
